Related Tracks
Related Tracks is a browse mode on club players that filters your own library against the track currently loaded — same key, similar tempo, same genre — so the next choice comes from a shortlist instead of the whole stick.
In practice
Let the player narrow the stick and let yourself pick from what is left. It filters fields, it does not know rooms.
Set the criteria before the gig rather than during it — key and BPM range are the two that earn their place, and genre only if your tags are consistent. Then treat the result as a shortlist to choose from rather than an answer to accept, because everything it knows came out of a metadata field. It is at its best in the moment when a plan has fallen apart and you need three plausible options in five seconds.

Where these come from: How the Related Tracks browse filter is configured on Pioneer media players — documented behaviour, not catalog figures. For what we can measure, see the key logic behind it.
Why it matters
It exists because browsing a large stick under pressure is genuinely hard. A player that can narrow four thousand tracks to the twelve that fit what is playing has removed the part of the job that goes wrong when a room is watching.
What it cannot do is know your library the way you do. It filters on the fields stored with each track, so it is only as good as your keys, your grids and your genre tags — and it has no idea which of those twelve records has ever worked in a room like this one.
Frequently asked
How does Related Tracks decide what is related?+
By filtering your own library on stored fields — key, tempo, genre and similar — against the loaded track. It is a filter over your metadata rather than any judgement about the music.
Why does it return nothing?+
Usually because the criteria are too narrow or the fields are empty. A stick where half the tracks have no key analysed has very little to filter on.
Is it the same as a recommendation?+
No. It narrows what is already on your stick by matching fields; a recommendation suggests records you do not own and considers how two tracks actually behave together.

Search filter
The search filter narrows the browse list on a player by typed text or by field — genre, artist, key, BPM band, rating, colour — so you can find a track on a stick of thousands without scrolling through them.
Smart playlist
A smart playlist is a saved rule rather than a saved list. You describe what belongs in it — tempo band, genre, rating, date range — and the software fills and refills it as the library changes.
Harmonic mixing
Harmonic mixing means choosing the next track by key as well as tempo — staying on the same Camelot code, moving one step around the wheel, or swapping between the major and minor of the same number.
Key detection
Key detection estimates a track’s musical key from the audio by measuring which pitches dominate and matching that profile against major and minor templates. It is an estimate, and it is confident even when wrong.
